If you are looking for information about "Metal detectors": the following search results will help you to find out what Metal detectors means.
| 1 | Metal |
| For alternative meanings see metal (disambiguation). A metal is an element that readily forms cations and bonds ionically. The metals are one of the three groups of elements as distinguished by..., a diagonal line drawn from boron (B) to polonium (Po) separates the metals from the nonmetals ... | |
| 2 | Metal detector |
| A U.S. Army soldier uses a metal detector to search for weapons and ammunition in Iraq Metal detectors use electromagnetic induction to detect metal. In 1881, Alexander Graham Bell constructed a crude metal detector in an attempt to find an assassin's bullet in President James Garfield ... | |
| 3 | Particle detector |
| In experimental particle physics, a particle detector is a device used to track and identify high... accelerator. Detectors designed for modern accelerators are huge, both in size and in cost. Types of detectors Bubble chamber Cherenkov detector. Cloud chamber Geiger-Mueller tube Photographic plates ... | |
| 4 | Polish mine detector |
| The Mine detector (Polish) Mark I was developed during World War II in the winter of 1941/1942 by Polish lieutenant Jozef Stanislaw Kozacki. His design was accepted and 500 mine detectors were... developments of the mine detector ( Mk. II , Mk. III and Mk IV ). The Mine detector (Polish) Mk. III was ... | |
| 5 | Angular misalignment loss |
| Angular misalignment loss : Power loss caused by the deviation from optimum angular alignment of the axes of source to waveguide, waveguide to waveguide, or waveguide to detector. Note 1: The waveguide may be dielectric (an optical fiber) or metallic. Note 2: Angular misalignment loss does not ... | |
| 6 | ALEPH detector |
| ALEPH (Apparatus for LEP Physics at CERN) is one of the four detectors of the LEP collider ... | |
| 7 | Semiconductor detector |
| A semiconductor particle detector is a device that uses a semiconductor (usually silicon) to detect the passage of charged particles. In the field of particle physics, these detectors are usually known as silicon detectors. Most silicon detectors work, in principle, by doping narrow (usually ... | |
| 8 | Envelope detector |
| An envelope detector is a device which is used to demodulate AM signals. The original message is.... Diode Detector The simplest form of envelope detector is the diode detector . To construct a diode detector, simply connect a diode between the input and output of a circuit, and connect a resistor and ... | |
| 9 | Greenleaf Whittier Pickard |
| experimented with contact detectors, used in crystal radio receivers. In 1906 he patented a silicon crystal detector. Picard's detector was revolutionary in that he found that a fine point in ... | |
| 10 | Antarctic Muon And Neutrino Detector Array |
| The Antarctic Muon And Neutrino Detector Array is a neutrino telescope buried under approxametly 1.5 to 2 Km of ice at the Antarctic ice cap ... | |

| 12 | Observational cosmology |
| Observational cosmology is the study of the structure, the evolution and the origin of the universe through observation, using instruments such as telescopes and cosmic ray detectors ... | |
| 13 | Smoke detector |
| Residential ceiling-mounted smoke detector A smoke detector is a safety device that detects.... Most smoke detectors work either by optical detection or by ionization, but some of them use both detection methods to increase sensitivity to smoke. Optical detector This type of detector includes a ... | |
| 14 | Costas loop |
| quadrature outputs, one to each of two phase detectors, i.e., product detectors. The same phase of the input signal is also applied to both phase detectors and the output of each phase detector is passed through a low-pass filter. The outputs of these low-pass filters are inputs to another phase detector ... | |
| 15 | Neutrino astronomy |
| for 10^36 target atoms. One such interaction would produce just a few photons. Neutrino detectors are generally formed from a large reserve of transparent detector material, ringed by photomultipliers to detect the brief flashes. Previously, detectors have been built by placing a large volume of ... |
